DH and I drew up mirror wills about a decade ago. All very straightforward - if I go first he gets the lot, if he dies first I get the lot, after both of us die, all split in thirds between the kids. Very simple.
At the time we named our respective fathers as executors. My dad is now living with quite advanced dementia and most definitely does not have capacity. DH's father still has capacity but is 80 and with the best will, won't be here forever.
I am assuming we need to make an appointment to see the lawyer and give details of who we wish to name as new executors? Or will they do it taking instruction by email or over the phone? Will probably be our oldest child, who was still at Primary school when the wills were drawn up, but is now 20.
